此外,本文还阐述了频率步进信号的逆傅立叶变换合成距离高分辨的处理方法,并对多散射点目标的合成距离高分辨效果进行了计算机仿真。
As an implementing method of multi - carrier modulation ( mcm ) , discrete multi - tone ( dmt ) modulation uses inverse discrete fourier transform ( idft ) vector as its modulating vector , and discrete " fourier transibrm ( dft ) vector as its demodulating vector , and the process of modulating and demodulating can be realized by using their fast calculating method
作为多载波调制的一种实现形式，离散多音频( dmt )调制分别采用逆傅立叶变换矢量和傅立叶变换矢量作为调制矢量和解调矢量，从而调制和解调过程可以利用这两种变换的快速算法实现。
